Abstract

Dynamic response of a multi-storey asymmetrical space frame structures having six degrees of freedom (three translations along x, y, z-axes and three rotations about these axes) at each node, with multiple tuned mass dampers (MTMD) on its top is obtained. Each tuned mass damper (TMD) is modeled using a two-noded element having two translational degrees of freedom at each node. MTMD with uniformly distributed frequencies are considered for this purpose. The effectiveness of MTMD in suppressing the structural response is determined by comparing the response of corresponding structure without MTMD. It is found that the MTMD can be used effectively to suppress the translational and rotational responses of the asymmetrical structures.
